Room-by-room heat load
We calculate heating and cooling requirements for each room individually. Floor area alone tells you very little — a south-facing room with large glazing has fundamentally different needs to a small insulated bedroom.

Mitsubishi Electric Ducted Systems
Premium Mitsubishi Electric ducted heating and cooling systems professionally designed for Canterbury homes.
What is a ducted heat pump?
A ducted heat pump provides discreet heating and cooling throughout the home via ceiling diffusers, while the main indoor unit and ducting remain concealed in the roof space. The result is even, quiet, whole-home comfort with no wall-mounted units.
Unlike individual high-wall units, a ducted system is designed as a single integrated solution — one outdoor unit, one indoor unit, and a carefully engineered duct network serving every room.

Why ducted heating?
Why system design matters
A ducted heat pump is only as good as the design behind it. We engineer every system around the factors that actually determine comfort.
Technical Design
We calculate heating and cooling requirements for each room individually. Floor area alone tells you very little — a south-facing room with large glazing has fundamentally different needs to a small insulated bedroom.
Supply air must reach every room at the right volume and velocity. We design throw, spread and drop characteristics so conditioned air mixes evenly without creating drafts.
Undersized ducts restrict airflow and increase noise. Oversized ducts reduce velocity and waste energy. Each run is sized for the airflow it needs to carry.
Correctly positioned supply diffusers deliver conditioned air where it's needed. Poor placement is a common cause of uneven temperatures and complaints.
Return-air paths are just as important as supply. A system cannot deliver air it cannot recover. We size and position return-air grilles to balance the whole system.
Different rooms suit different diffusers. We select from linear slot, round, square and architectural grilles based on ceiling type, airflow and aesthetic requirements.
Every duct system has a static pressure the fan must work against. We design the duct network so external static pressure stays within the unit's operating range.
Zoning allows different areas to be conditioned independently. We design zone dampers into the ductwork from the start rather than bolting them on later.

Installation & Commissioning
Installation quality means workmanship, neatness, duct support and routing, insulation, sealing, access and serviceability. The installation is not complete when the system switches on.
Professional commissioning includes airflow setup, balancing, static-pressure configuration, controller setup, system testing and client handover. This is what turns a collection of components into a properly functioning comfort system.
Frequently Asked Questions
Pricing depends on home layout, required capacity, number of rooms, duct design, zoning, controls, ventilation and installation complexity. Because every home is different, we provide a tailored proposal after assessing the property. We don't quote a fixed price because a properly designed system is never a one-size-fits-all product.
Square metres alone are insufficient. A proper heat-load calculation considers glazing, insulation, orientation, ceiling height and room-by-room requirements. A home with the same floor area can need very different capacity depending on how it's built.
A ducted heat pump installation typically takes one to three days, depending on the system specification.
Yes—we prefer clients to be at home during ducted installation so we can discuss and confirm grille positions with you as the work progresses.
Your quote includes everything required for the agreed installation, including old-system removal where applicable, electrical work, commissioning, controller setup and clean-up. All electrical work is carried out by a registered electrical contractor. The price changes only if you change the agreed specification. Any plastering or painting you need to arrange separately will be discussed before installation.
Additional ceiling access openings are not generally required. If an opening is needed, we will discuss it with you before installation. We generally recommend engaging your own plasterer and painter to complete any associated repairs and decorating.
Daniel personally assesses your home in person and discusses the available options with you. This helps establish a suitable system and installation approach for your property before the work begins.
A standard ducted system includes a wall controller with a seven-day timer. Wi-Fi control and zoning are optional upgrades. Your quote will clearly identify the controls included in your installation.
Yes. At handover, we give you a full explanation of how your system and controls work, including how to clean the filters. We also advise when your system is due for servicing.
We allow for follow-up visits to fine-tune airflow to suit your comfort. If you have questions, you can call Daniel directly. If he is unavailable, he will return your call as soon as he can. Our installations are also backed by a five-year workmanship warranty.
Yes. Mitsubishi Electric Lossnay ventilation can be integrated with a ducted heat pump system, introducing filtered fresh air while recovering heat energy. We design the two systems to work together as one.
With zone control, different areas of the home can be conditioned independently. This allows individual room comfort and reduces conditioning of unused spaces.
Yes — and we also review the existing duct system rather than automatically connecting a new unit to poorly designed ductwork. In many cases upgrading the duct design is what actually fixes the comfort problem.
Yes, particularly for replacement and upgrade installations. Our premium positioning applies regardless of system type — every installation is designed, not just fitted.
Mitsubishi Electric exclusively. We've chosen to specialise rather than offer numerous competing brands, so we can deliver deeper expertise and better long-term support.
Multi-Room Comfort
Where ducted isn't practical, a multi-room system provides comfort across multiple rooms from one outdoor unit.
